1. The destruction or killing of the fetus or causing an abortion.
2. The destruction of the embryo or foetus in the uterus.
3. The intentional destruction of a human fetus; for example, by using an agent or drug.

Feticide, as a legal term, refers to the deliberate or incidental killing of a fetus as a result of a human act; such as, a punch or kick in the abdomen of a pregnant woman. It does not refer to the death of a fetus from entirely natural causes, or through the spontaneous abortion of a pregnancy where the life of the fetus could not be maintained artificially ex utero.
